w1: therm: Fix off-by-one buffer overflow in alarms_store

2025-12-18T16:01:42Z

The sysfs buffer passed to alarms_store() is allocated with 'size + 1' bytes and a NUL terminator is appended. However, the 'size' argument does not account for this extra byte. The original code then allocated 'size' bytes and used strcpy() to copy 'buf', which always writes one byte past the allocated buffer since strcpy() copies until the NUL terminator at index 'size'. Fix this by parsing the 'buf' parameter directly using simple_strtoll() without allocating any intermediate memory or string copying. This removes the overflow while simplifying the code.

w1: ds28e17: Replace deprecated strcpy + strcat in w1_f19_add_slave

2025-10-13T00:19:03Z

strcpy() is deprecated and using strcat() is discouraged. Replace them with scnprintf(). No functional changes. Link: https://github.com/KSPP/linux/issues/88 Signed-off-by: Thorsten Blum Signed-off-by: Krzysztof Kozlowski

sysfs: treewide: switch back to attribute_group::bin_attrs

2025-06-17T08:44:15Z

The normal bin_attrs field can now handle const pointers. This makes the _new variant unnecessary. Switch all users back. Signed-off-by: Thomas Weißschuh Link: https://lore.kernel.org/r/20250530-sysfs-const-bin_attr-final-v3-4-724bfcf05b99@weissschuh.net Signed-off-by: Greg Kroah-Hartman

sysfs: treewide: switch back to bin_attribute::read()/write()

2025-06-17T08:44:13Z

The bin_attribute argument of bin_attribute::read() is now const. This makes the _new() callbacks unnecessary. Switch all users back.

w1: ds2406: use crc16() instead of crc16_byte() loop

2025-05-14T03:37:16Z

Instead of looping through each byte and calling crc16_byte(), instead just call crc16() on the whole buffer. No functional change. Acked-by: Krzysztof Kozlowski Acked-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20250513022115.39109-2-ebiggers@kernel.org Signed-off-by: Eric Biggers

w1: core: use sysfs_emit() instead of sprintf()

2024-12-22T14:42:15Z

Follow the advice in Documentation/filesystems/sysfs.rst: show() should only use sysfs_emit() or sysfs_emit_at() when formatting the value to be returned to user space.
